Abstract
- Radiation-induced changes in the optical properties of fluoride glasses (FGs) were studied on samples of zirconium fluoride and aluminum fluoride based compositions gamma-irradiated to a total dose of 1.2 MGy. Upon exposure, the fundamental absorption edge smears and shifts toward longer wavelengths. The FGs studied exhibit self-recovery of the optical properties, whereby the radiation-induced absorption decreases in the course of storage without action of any external factors. Photostimulated recovery of the optical properties of the gamma-irradiated FGs was studied in the range of light wavelengths from 400 to 1200 nm at a light intensity of 1–3 mW/cm2. The maximum rate of recovery for both zirconium and aluminum fluoride based glasses was observed for the photoannealing at 600 nm.
